Threaded press-in inserts for plastics 21 June 2024

E-Z Lok, a manufacturer and distributor of threaded inserts for metal, plastics and wood, has introduced the E-Z Press™ inserts, specially designed for post-moulding installation in either thermoset plastics or thermoplastics. 

A slotted design with a diamond knurled outside diameter allows for ‘cold’ installation, which also enables optimum torque and pull-out resistance. Cold installation of threaded inserts reduces the costs of mouldings and eliminates the need to ‘chase’ threads after moulding. Furthermore, they also help to reduce waste caused by misaligned and faulty inserts and assist in proper installation when there is no precise hole depth. 

When the E-Z Press™ insert is installed, it compresses slightly along the slot. As the fastener is threaded into place, the insert expands and the diamond knurl is pressed into the wall of the hole, securing the insert in place.  

E-Z Press™ inserts are available in three styles – flush, flanged and reverse slot. All three types press into place for fast and easy installation, and anything from a rubber mallet to an arbor press can be used for installation.
